Probably your mother always said that carrots are good for your eyes and you need to eat them. But is this really the case? The story about carrots began in WW2. The British said that their pilots ate lots of carrots and therefore could see well in the dark and so they knew where they should attack. But actually, the Brits just had a radar.
Later it is found that roots actually are good for the eyes. Carrots contain beta-carotene, which is converted in the body into vitamin A. This is later converted to a specific substance that is in your eye, which ensures that you can see whether it is light or dark. It is therefore important that you get enough vitamin A to support your eyes. It is not true that you can improve eyesight by ingesting large amounts of vitamin A, it is ‘only’ for support of your eyes.
When someone suffers from certain conditions such as genetic disorders, aging or diabetes, eye vision can be reduced. Sight reduction by one of these causes cannot be remedied by eating vitamin A.
There are currently two nutrients which have been known to support the functioning of the eye, namely: lutein and zeaxanthin. The foods which are therefore good for the eyes are mainly: carrots and green leafy vegetables such as spinach, kale, and collard greens.
